Watch the Week 7: Modal Techniques for Fretboard Building online guitar lesson by Joe Pinnavaia from Fretboard Powerup
This lesson is focused on the viewing of several keys in one position by playing through the modes in one position. This can be done anywhere on the fretboard. The goal is to enable you to "see" key changes as they happen and ultimately will bolster your knowledge of the fretboard. This is a long term goal and if you make this a part of your daily routine for sometime you will notice big changes in how you see and use notes on the fretboard.
